February 2017
Automatic Mode
OUT status is set to Good: Cascade. The limit status of the selected input (SEL_1, SEL_2 or SEL_3) is also copied to OUT.
The status and value of the BKCAL_SEL_1, BKCAL_SEL_2 or BKCAL_SEL_3 parameter corresponding to the selected
input is set equal to the OUT status and value. When the OUT status is limited, its limit status is also copied to the
associated BKCAL_SEL[x] parameter and its value is set equal to the selected input value. When the OUT status is not
limited but the BKCAL_IN status from the downstream block indicates it is limited, the BKCAL_IN limit status and value
is copied to the associated BKCAL_SEL[x] parameter.
The status and value of the BKCAL_SEL[x] parameters that do not correspond to the selected input (the non-selected
BKCAL_SEL[x] parameters) are set equal to the status and value of the BKCAL_SEL[x] parameter that corresponds to
the selected input after its value and status is determined as above. The substatus of the non-selected BKCAL_SEL(x)
parameters are set to Not Selected.
When the SEL_TYPE is Low value, the limit status of the non-selected BKCAL_SEL(x) parameters are set to High
Limited. When the SEL_TYPE is High value, the limit status of the non-selected BKCAL_SEL(x) parameters are set to
Low Limited. When the SEL_TYPE is Middle value, the limit status of the BKCAL_SEL(x) that corresponds to the lowest
SEL(x) input is set to Low Limited. The limit status of the BKCAL_SEL(x) that corresponds to the highest SEL(x) input is
set to High Limited.
Initializing Manual Mode
When the BKCAL_IN status indicates Initiate Request (IR), the status of OUT is set to Good: Cascade, Initiate
Acknowledge (IA). Otherwise, the status of OUT is set to Good: Cascade. The value of OUT is set equal to the value of
BKCAL_IN. The value and status of BKCAL_SEL_1, BKCAL_SEL_2 and BKCAL_SEL_3 are set to the value and status of
BKCAL_IN.
Out of service Mode
The statuses of all output parameters are set to Bad: Out of Service.
